Social and environmental issues continue their upward march in importance to shareholders, comprising nearly half of all shareholder proposals filed this proxy season so far, according to proxy advisory firm Institutional Shareholder Services.

Even if not all of those proposals will come to a vote—and many surely will not—they indicate that the wellspring of interest in such issues is not flagging. Environmental and social proposals constituted 40 percent of all proxy resolutions last year, ISS says, and the topics have clearly reached a new level of attention to the investor’s mind.
